The influence of the growth of three higher fungi on the composition of wheat straw was investigated. Pleurotus pulmonarius, P. sajor-caju and Lentinus edodes grew very well on lignocellulosic substrates, breaking down a considerable amount of lignin. The initial lignin concentration of straw was halved after 12 weeks of fungal growth, doubling the enzymic digestibility. Together with lignin, the higher fungi consumed half of the amount of hemicellulose (i.e. 15%), leaving cellulose fairly intact, which should remain as an energy source for ruminants.
